The Microchip PIC16C64A-04/P: A Robust 8-Bit CMOS Microcontroller with Integrated EEPROM

In the landscape of embedded control, the demand for reliable, versatile, and cost-effective microcontrollers remains constant. The Microchip PIC16C64A-04/P stands as a significant solution within this domain, representing a mature yet highly capable 8-bit architecture built on CMOS technology. This device is particularly distinguished by its integrated EEPROM data memory, a feature that provides exceptional flexibility for data storage in a wide array of applications.

As a member of the venerable PIC16Cxx family, this microcontroller is engineered for high performance and low power consumption. The CMOS technology is fundamental to its operation, enabling both high-speed computation and efficient power management, which is crucial for battery-powered or energy-sensitive designs. The "04" in its part number denotes a maximum operating frequency of 4 MHz, allowing for a balanced execution of instructions between processing speed and power efficiency.

The core strength of the PIC16C64A-04/P lies in its memory configuration. Beyond its 4K words of UV-erasable program memory, the inclusion of 128 bytes of EEPROM is its most impactful asset. Unlike standard RAM, which loses data when power is removed, this non-volatile EEPROM allows designers to store critical data—such as calibration constants, user settings, event counters, or system configuration parameters—that must be retained through power cycles. This eliminates the need for an external serial EEPROM chip, reducing overall system cost, board space, and complexity.

The peripheral set of the PIC16C64A-04/P is designed for comprehensive system control. It includes three I/O ports, a versatile timer/counter module with a prescaler, and a powerful interrupt structure. The device is well-suited for a multitude of tasks, from industrial control and automotive systems to sophisticated consumer products and intelligent sensors. Its 28-pin PDIP package ensures ease of prototyping and integration into various circuit designs.

ICGOODFIND: The Microchip PIC16C64A-04/P endures as a compelling choice for developers seeking a self-contained, full-featured microcontroller. Its integrated EEPROM technology provides a critical competitive advantage, simplifying design architecture and enhancing data integrity. For applications requiring dependable performance, non-volatile data storage, and proven reliability, this microcontroller continues to be a relevant and powerful component in an engineer's toolkit.
